Phase-locking of hippocampal theta and gamma waves has been proposed to support memory formation, but an analysis using robust statistical methods finds no convincing evidence for the phenomenon.
Integration and segregation of information of memory and sensory in the hippocampus could be achieved by the coordination of distinct theta-gamma coding frameworks.
Spatial accuracy of grid cell firing correlates with the slope of the local field potential theta frequency vs. running speed relationship and integrates velocity signals over past time.
Building on previous work (Sweeney-Reed et al., 2014), it is shown that the timing of the theta rhythm of the right anterior thalamic nucleus predicts human memory formation.
The contribution of biophysical ion channels to neuron function can be predicted by taking advantage of an ongoing dialogue between model and experiment.
Computational modelling shows that coupled theta and gamma oscillations in the auditory cortex can decompose speech into its syllabic constituents, and organize the neural spiking at faster timescale into a decodable format.
Variations in the frequency of theta brain waves enable a single network of brain regions to generate appropriate responses to stimuli with different kinds of emotional value.
Random fluctuations in neuronal firing may enable a single brain region, the medial entorhinal cortex, to perform distinct roles in cognition (by generating gamma waves) and spatial navigation (by producing a grid cell map).
Inhibitory noninvasive stimulation to the precuneus disrupts theta and gamma oscillatory coupling between medial temporal lobes and neocortical regions during complex personal memory retrieval.
